Ranveer Singh keeps a close tab!

Mumbai, June 7 -- He may be on a cruise liner in Spain, shooting for one film, but Ranveer Singh is just as involved with another project of his.

Despite being busy with Zoya Akhtar's film, the actor has been in constant touch with Shaad Ali, who is directing his next.

A source close to Ranveer reveals, "He has been calling Shaad every few days to check on the progress of the film. They've completed most of the shooting, so it's already in the post-production stage. One song is yet to be shot; they will do that when Ranveer is back in town next month. Since the film is releasing in November, there's plenty of time to go."

Apparently, the actor met Shaad even before leaving for Spain, and had a long chat with him.

"They met to figure out the details about the pending song, as well as check on how the film has shaped up so far. Ranveer is very hands-on with the project because it's his first solo release after a year," says the source, adding, "Although there is a strong supporting cast, his is the main and most important character in the film. In fact, he has been keeping in touch with producer Aditya Chopra as well."
